Question

Find the area of the quadrilateral below.

Give you answer in cm² and give any decimal answers to 1 d.p.

Answer 1

`36 \: cm ^(2)`

Explanation:

triangle area below

`(10 * 5)/(2) = 25`

EG segment

`\sqrt{10 ^(2) + 5 ^(2) } = √(125)`

EF segment

`\sqrt{ (√(125))^(2) - 2^(2) } = √(121)`

triangle area above

`( √(121) * 2)/(2) = √(121)`

total area

`25 + √(121) = 36`
